PROBLEM TO BE SOLVED: To provide a method for safely processing an electrolyte containing a volatile fluorine compound (LiPF, or the like) and an organic solvent.SOLUTION: The method for processing an electrolyte containing a fluorine compound includes a vaporization step for vaporizing the volatile components of an electrolyte containing a fluorine compound by heating it under reduced pressure, a fluorine fixing step for fixing the fluorine component contained in the vaporized gas as calcium fluoride by causing reaction with calcium, and an organic solvent component recovery step for recovering the organic solvent component contained in the vaporized gas. Preferably, volatile components of electrolyte are vaporized by heating the electrolyte under reduced pressure after adding a small quantity of water thereto. |
